HDMI-CEC chooses the source (and its power on/off) for your HDTV based on which HDMI input has the CEC handshake. But the 8642HDC doesn't support the handshake
Holding down the power button on the URC-8820 remote turns EVERYTHING ON... requiring you to manually (using the remote) turn off the DVD/BluRay and AUX to get just the TV and STB (set-top box).
Then I ran across a description of an AT8400 remote that can be programmed to only turn on certain devices. Can the Cox URC-8820 remote be so programmed?

The UEI URC-8820 is macro-programmable to do partial or all on/off.
I tried the UEI codes, but they didn't work.
Does anyone know if Cox' (UEI) URC-8820 is macro-programmable? And how to do it?
The Cox remotes have just the one preset macro program that I know of. That is the holding down power for it to cycle power on all devices. As Far as setting up your own macro program I could not find that in the manual for the Remote I have. I have the silver faced one not sure what model number.
